AUGUST W. SOHULENBURG, OF ST. LOUIS, MISSOURI.

DEVICE FOR MOISTENINQ THE AIR FOR HOT-AIR FURNACES AND STEAM-HEATING.

SPECIFICATION forming part of Letters Patent No. 373.858, dated November29, 1887.

Application filed September '7, 1886. Serial No. 212,964. (No model.)

To all whom it may concern:

Be it known that I, AUGUST W. SOHULEN- BURG, a citizen of the UnitedStates, residing at St. Louis and State of Missouri, have invented a newand useful Improved Device for Moistening the Air for Hot-Air Furnacesand Steam-Heating, of which the following is a specification.

It is well known that where hot-air furnaces or steam-heating is usedfor heating buildings the air throughout the rooms and balls is of aparched and dry nature, renderingit unpleasant and often unbearable totheinmates. The usual way to overcome this and render the air moist isthe placing of a water-pan containing Water in the chamber of thehot-air furnace or steamheating apparatus, but always of such smallevaporating-surface that it practically The object of my invention istherefore, by means of the device hereinafter explained, which hasextended evaporating-surfaces and admits of the free passage of the hotair,whereby the particles of dry parched air are thoroughly moistened,to diffuse an equable pleas ant air throughout the rooms and halls ofthe building.

Of the drawings, Figure l is a perspective view of my device, showingthe series of channels a a a a and sectional View of lateral chan nel b.Fig. 2 is a sectional view, also showing section of inclosing hot-airpipe B. Fig. 3 is a perspective view as applied to register of room orhall, also showing auxiliary watertank D for the automatic supply ofwater. Fig. 4 is a perspective view as applied to coil of steam pipes orradiator and auxiliary tank D. Fig. 5 is a perspective view as appliedand placed inside of a furnace-chamber and auxiliary tank D.

Similarletters referto similar parts throughout the views.

As shown and illustrated in the drawings, A is my device orair-moistener, which I construct as aseries of channels or receptacles,aa a a, open at the top, having lateral feedchannel I), also open at thetop, as shown in Figs. 1 and 2. Said channels a a a a, I make,

' or more wide.

say, one-eighth of an inch or more in width. Lateral feed-channel b, Imake, say, one inch or other material, of suitable number, depth, andsize, each of said channels having sides a a closed at the bottom candone side, 0, and merge or unite them to the lateral feed-channel b atthe side a, as shown in Figs. 1 and 2. In order to permit of the escapeof the hot air, =1 space each of said channels a a a a one inch or moreapart in their whole length, beginning at the intersection of saidlateral feedchannel I). The escape of the hot air is indicated by thearrows in said spaces. The vessel so constructed I fasten together bybands (I at the top, bottom, andsides.

It will be readily seen that the construction of my device is such thatwhen applied for its purpose the sides a a of each of the series ofchannels a a a a, in combination, give large evaporating-surfaces to theparticles of dry air issuing from the hot'air furnace or steamheatingapparatus, rendering the air moist and pleasant in its passage throughthe spaces of the series of said channels.

I apply my device or air-moistener as de-' scribed to register in thesecond story of any building by taking up the same and replacing afterhaving seated the vessel in the hot-air flue in other situations, asshown in the drawings-Figs. 3, 4, and 5, for example-to register offirst story or radiator of a steamheating apparatus, or when applied tointerior of the furnace-chamber. For the better continuous and automaticsupply of the water, I construct and place adjoining my said deviceauxiliary water-tank D, which I connect to same by a flexible rubberhose, said auxiliary tank being so arranged by a suitable adjustment ofweights as to automatically feed water to the air-moistener and keep thesame at its proper level.

In practice box A and tank D are made of equal capacity, and the latteris filled only slightly above opening of the supply-tube, and if theweight attached to said box should sud denly raise the same in case thewater evaporated too rapidly there would be no overflow in box A. V

I am aware of the Patents No. 31,152, of January 22, 1861, No. 99,864,of February 15, 1870, and No. 152,744, of July 7, 1874, their Thesechannels I form of tin construction, and operation of their variousposition in close proximity to said box, subparts, and therefore do notclaim the same. stantially as and for the purpose set forth. to

Vhat I claim is- In testimony of said invention I have here-Anair-moistening device for furnaces, connnto set my hand. 5 sisting ofa channeled box inclosing the outer AUGUST WV. SOHULENBURG.
